These reflections on liberation and spirituality respond to a precise question. People committed to action in behalf of liberation need a spirituality. The issue is not why Christian spirituality needs to be attentive to the demands of the poor and other victims of discrimination. A slightly different issue is at stake in the question of what spirituality, present in Christianity, is summoned forth when people who are dedicated to the project of liberation turn to Christianity and ask about its spiritual resources. Here, Haight explores the language of liberation and spirituality and brings forward four classic witnesses to Christian spirituality and allows each to highlight a particular element of an integral Christian spirituality.
